Current State (August 2025)

The dotfiles have evolved into a sophisticated, modern development environment featuring:

  • Neovim with LazyVim and comprehensive LSP/DAP support
  • Alacritty terminal with optimized performance
  • tmux for session management with vim-like navigation
  • Mason for automated tool management
  • mise for environment/version management
  • AI-assisted development workflows

This represents a complete transformation from the original 2013 bash-based setup to a cutting-edge development environment optimized for modern software development workflows.

o3:
Below is a high-level timeline of how this dot-files repository has evolved since its creation. I have grouped the history by period and called out the most significant changes, using both the commit messages and the relative size / nature of the diffs to decide what mattered.

2013 ‑ Foundations
• Jan 2013 – First commit adds the core Bash startup files (aliases, env, bashrc). Immediately afterwards the large 2 400-line git-completion.bash script is imported.
• Apr 2013 – PATH tweaks, hostname in prompt, and a cleanup of virtual-env handling.
• Apr 2013 – Vim arrives: vimrc plus colour scheme (≈260 loc).
• Apr 2013 – Git configuration is added and install / uninstall helper scripts are written (≈80 loc each).
• Apr–May 2013 – Custom Vim syntax files for scientific codes (CHARMM, deMon) are developed and iterated.
• Aug 2013 – Install script now makes safety backups instead of overwriting user files.

2014 ‑ Tooling Explosion & Shell Migration
• Jan 2014 – CoffeeScript syntax, Bash env cleanup.
• Mar 2014 – pathogen is committed (344 loc) to manage Vim plugins; solarized colour scheme (1 100 loc) added soon after.
• Jun 2014 – Huge jump: Z-shell adopted. Adds zshrc, aliases, env (≈2 300 added / 2 000 deleted lines – the repo effectively switches its default shell).
• Jul 2014 – Sensitive env treated via .gitignore.
• Aug 2014 – Major “refresh”: big diff that removes the old install scripts and prunes many lines; Bash vs Zsh duplicated config consolidated.

2015 ‑ Workflow polish
• Nov 2015 – Full tmux setup introduced (tmux.conf, completions, tmuxinator templates, ≈120 loc). Repo now covers shell, editor and terminal multiplexer.
• 2015 throughout – rbenv/pyenv, git-lfs, clip-board fixes, Vim plugins (CtrlP, vim-rails), JS highlighting. Mostly small targeted diffs.

2016 ‑ Consolidation & Cleanup
• Jul 2016 – Big refactor: Bash and Zsh configs merged; many duplicate files deleted (net −78 loc, +74 loc).
• Apr 2016 – Custom Vim syntax files deleted in favour of external plugins (−300 loc) and colour schemes removed (−1 300 loc).
• Late 2016 – Vim-airline replaces earlier statusline; tmux and Vim status bars synchronised; clipboard integration for macOS Sierra.

2017-2019 ‑ Home-machine automation
• 2017 – Brewfile introduced and subsequently updated many times to trace the homebrew software stack.
• 2017 – iTerm2 preferences plist committed (thousands of lines) and then moved/renamed repeatedly.
• 2018-2019 – Gradual pruning of unused tmuxinator configs, switch to tmux 2.9, global/local gitignore separation, more aliases.

2020 ‑ Modularisation
• Jan 2020 – Directory restructure (iterm2/, brew/, git/, tmux/, zsh/ etc.) with massive file moves; Vim config split into vim/ sub-folder.
• Apr 2020 – Minimal Brewfile variant, nvim/init.vim appears – first step toward Neovim.
• Sep 2020 – Starship prompt adopted, fzf/ripgrep/bat tooling added, tmux copy-mode tweaks.

2021-2022 ‑ Terminal & Prompt overhaul
• 2021 – iTerm2 plist dropped to reduce noise (−2 500 loc). Alacritty config added; shift away from iTerm2.
• 2022 – Zsh startup guards for version-manager binaries.

2023 ‑ Modernisation
• Sep 2023 – Alacritty theme work, nvim plugins pruned; git completion script removed (−2 700 loc) and replaced by Homebrew version.
• Late 2023 – New tooling: skhd keybindings, Starship prompt, global git config moved to XDG path; FZF settings tuned.

2024 ‑ Full Neovim & Lua
• Jan 2024 – Neovim config migrates to init.lua + Lazy-vim lock-file; old init.vim removed.
• Feb 2024 – Large tmux rewrite: custom helper scripts (tmux-layoutizer.sh, etc.) and dynamic status-right.
• Mar 2024 – Sketchybar & Karabiner configs appear; Alacritty theming organised in themes/ directory.

2025 ‑ IDE-like Dotfiles
• Feb 2025 – Shift back to simpler tmux status; repo stabilises after experimentation.
• Mar–Jun 2025 – Neovim super-charged: Mason manages LSP & DAP, Lazy-vim plugin set curated; Rose-Pine/Monokai themes added; keymaps aligned with tmux; heavy cleanup of legacy shell scripts.
• Aug 2025 – Post-migration tweaks for new machine; mise version manager config; removal of unused tmux helpers; further Neovim tuning.
• Aug 2025 – User-level DAP configs committed (j2de.lua) finalising the modern dev-environment.

Key Evolution Themes

  1. Shell → Zsh (2014) and later Starship prompt (2020-24).
  2. Editor → Vim → Neovim with Lua-based config and plugin manager (2020-25).
  3. Terminal → iTerm2 plist heavy era → move to Alacritty (2021).
  4. Multiplexer → tmux introduced 2015, iterated with custom scripts & statusline integration.
  5. Tooling/Automation → Homebrew Brewfile, skhd, karabiner, sketchybar, mise.
  6. Continuous cleanup cycles – large deletions of now-external plugins/configs keep repo lean.

Overall, the repository chronicles a gradual ascent from a few ad-hoc Bash aliases to a fully scripted, theme-able workstation environment driven by Zsh, Neovim-Lua, tmux and Alacritty, with strong attention to cross-tool keybinding parity and automated package / version management.
